Aluminum-coated kraft paper bag with three-side seal packaging.

Common leisure foods, rice, tea, facial masks, and other products found in supermarkets are often packaged using three-side seal bags. In terms of bag style, the three-side seal bag is the simplest and most common. Its design features three sealed sides and one open side, leaving only one opening for users to fill with products. Its advantages include: excellent air tightness, outstanding moisture retention, and sealing performance; high barrier properties with extremely low oxygen and moisture permeability; strong resistance to dampness and mold; a bright and aesthetically pleasing appearance, non-toxic and odorless; the ability to be expanded into a three-dimensional bag shape after formation, offering high space utilization efficiency.
In addition to the points mentioned above, three-side seal bags have strong extensibility and can be customized according to needs. Features such as resealable zippers, easy-tear notches, and hanging holes for shelf display can all be implemented on three-side seal bags. 655
